UNITED/erstes FRANK J. KERBER, 0F CHICAGQ, ILLINOIS. 'K I BUMPERETTE.

Application led December My invention relates to bumpers for automobilesiand more sarticularly to that tyoe known asbumperettes, which are especially adapted for the rear of the automobile and adapted to leave or provide a space between the saine for the accommodation et tire rack and tire or tires, a trunk or the like, and at the saine time effectively proto t the rear tenders., wheels, body and spare tire or trunk and in general, the rear of the machine7 troni the iin-` pacts with other cars or objects as it is thought will be readily understood. s ,Y

Among the objects of the invention are to' provide `a novel construction or' bumper or bumperetto"A- so-called, of .the type referred to,

produced eGenomically7 but which at the ne time, is oil a high class character and of the best materials; which embodies all ofthe iest essentials of an impact inembe" to take the impacts of other machines andaU provide the necessary resiliency to reduce the transmission oi' jar without injury themL idity to the car, while givingthe required il@ or strength to prevent injury or dis-torti the bumperette;'to provide added resinene,"

without impairingl the ability et the' devices to absorb shocks and to facilitate the mountn ingI of the bumperettes on various types and styles of cars. A f y Other and further objects Vof the invent will be readily apparent as the descript proceeds. ,y

Referring to the drawings in detail, in which like reference characters designate like parts throughout the several views, l designates an lautomobile having the usual rear 'fenders y'gasoline tank 6 and rear tire 7 supported in the usual or any preierred manner by a tire holder or rack, not shown, but which is common in the art, or there may be provided a trunk with or withouttlie 1e holder in such a manner to project een* j from the rear of the car body and gasoline tank, tlius rendering a bumper which entends across the the same time.

entire back undesirablel and unsightlyas well as incouveni so tar as the mounting and removal ot the spiare tire is concerned.

The chassis is provided wito the usual side members or bars 8 which curve downwardly the rear and havetlie rear ysprings 9 conn nected thereto by the shackles l0 through the medium oit the shackle bolts ll. fillet the parts hei )fore describ= i ay be oi1 any well known or standard consafuctiou and no claim et' novelty is made thereto. ',.if'lie bumperette perticularly comprising my invention consists of a novel construction and arrangement oitparts, and as shown, is made up ot-a spring metal ilat ber l2 preferably steel, having` its forward c li i othe' 'sse oruied with ana4 i/cliiug'portion 13 which is bolted to the side kof the channel c'de bar S ot the cliass' or :traine as indiat lil?. simply by perifere/ing the same o se clamped-thereto. The

extended inrear end oit' the bar l2 is l angle as shown ward'u at substantially a right at l5 above and .in rear of the, downwardly fed rear oortion oi the side member of the il anic, preferably in slightly spaced relation tl'icretous shown, and in a. horizontal position or substantially so. A similar bar 16 is placed alongside of the bar l2 and bolted thereto two or more points and to the side member, indicated at l? and 18 and its rear end 19 placed against the end l5, both be'ngg apertured, as shown to receive a bolt 20. rilhe portion 13 provides a substantial bearing' for the device and attachment means there for. y v

Y The forward end of the bar 16 is curved or extended outwardlyfor a considerable distance in rear or beyond the wheel tender in a substantially reverse o r ogce curvej iirst outwardly rearwardly as at 2l then torwardly as at'22, with the free end extend ing at a slight outward angle or substantially 'parallel to the side of the chassisj as shown.

VLMef'cd or bent upwardlyU or ing and absorbing the impacts from the rear and at the side.

In addition, there is interposed at the rear, a cushion member or sleeve 25, of rubber or other suitable material, said sleeve being positioned between the inner end of the bar 24 and the bent end 19 and the bolt 20 being passed through all of said parts so that an impact will cause thel sleeve or resilient cushion member to be compressed and the bolt 2O freely slide through the parts 15 and 19 and give slightly to the impact, while at the same time absorbing it. The idea in providing the pair or plurality of bars 12and 16, is to provide the necessary rigidity or stiffness to give strength to resist impact without bending or injuring the chassis and adjacent parts, and at the same time, to give greater resiliency tl an would be provided by a single bar of the combined thickness of t-he two bars 12 and 16, in addition to facilitating manufacture economically with lighter ma- `terial and the attachment of the device to the frame of the machine in an eflieient and substantially rigid manner, as provided by the upwardly extending portion 13. I-Iowever, it is to be understood that the attachment may be made in any eesirable and effective lmanner which will give the necessary results, and therefore I do not desire to be restricted to the exact construction and arrangement disclosed.

Moreover', while I have shownv the invention in the preferred form, itis to be understood that various modifications may be made in the construction withoutdeparting Afrom the principles and spirit of the invention so long as the same are within the scope of the device as claimed hereinafter.

I-Iaving thus described my invention, what I claim is:

1. A bumperette including a bar having its forward end angularly bent upwardly for attachment to the side bar of an automobile frame and having a resilient member extending outwardly from the forward'end thereof,

another member extending from the free end of the resilient member to a point in rear of the first bar, and a connection at the latter point with an interposed resilient member.

2. A bumperette including a Vbar for attachment to the side bar of `an automobile frame and having a spring member extending voutwardly from the inner end thereof, aV

curved member attached tothe free end of the spring member and extending rearwardly and inwardly, and a resilient connection between the curved member and the acentend at the outer part of the first bar. l 3. A bumperette comprising a bar for taehment to the side of an automobile chassis and having anoutwardly extending curved spring member at its forward end, an invwardly and rearwardly curved bar extending from the outer portion of the springmember and connected thereto, and a cushion member between the rear end ofthe irst'bar and the inner kend of the curved bar.

4t. A bumperette for mounting at the rear end of the side bar of an autoinobile'frame,

including a sectional'bar anchored to the side 7 l bars in contact and adapted'to attach to a` chassis, both having inwardly bent rear ends, one bar having at its forward end an outwardly extending portion with av compoundY curve, a curved bar connected to the outer f f end of the latter bar, and a 'compensating connection between the curved bar and the inwardly bent rear ends. f

In testimony whereof I afhx my signature.
